The previous government issued media alerts every time a boat arrived, but no new alerts have been issued since the new Government was sworn in.

The ABC asked both Customs and the Immigration Department whether any boats have arrived in recent days, but the questions were referred back to the Minister's office.

A spokesman for the Immigration Minister Scott Morrison would not say if any boats had arrived, and said further details about the Government's Operation Sovereign Borders policy would be provided soon.

"Updates will be provided on Operation Sovereign Borders. We will be making further comments on these matters next week," he said in a statement.
